Pratt & Whitney Canada and Viking Air Limited today announced they have entered into a 10-year General Terms Agreement to supply PT6 engines, including the PT6A-34 for the Twin Otter aircraft. The announcement was made during the National Business Aviation Association's 65th annual meeting and convention in Orlando, Florida. P&WC is a United Technologies Corp. company (NYSE:UTX).

"This agreement bears witness to the strong bond P&WC and Viking Air have always enjoyed," said Denis Parisien, vice-president, general aviation products, P&WC. "The Twin Otter and the PT6 have always been and continue to be inseparable."

An industry icon and Canadian treasure, the Twin Otter is recognized for its rugged reliability in all environments and ability to land on any surface. "We are excited the PT6 engine and the Twin Otter are renewing their relationship," said David Curtis, president & CEO of Viking. "Just as when a customer buys the Twin Otter they're getting more than an ordinary aircraft, by buying the PT6, we're getting more than an ordinary engine. The PT6 and the Twin Otter are extraordinary together, and continue to bring out the best in each other."

Known around the world for its reliability and durability, the PT6 has captured more than 130 applications for general and business aviation, helicopters, commuter, utility and trainer aircraft. With more than 49,000 engines delivered, and close to 400 million hours flown, the PT6 is the world's most popular engine in its class. Compared to the first PT6A model, today's engine is up to 4 times more powerful, with a 40% better power-to-weight ratio and up to 20% better specific fuel consumption (SFC).

"PT6 engines are used by 7,000 operators around the globe and stand as a testament to how P&WC reinvents its products to meet emerging customer needs," concluded Parisien. "Although other engine OEMs have tried, none have come close to matching the versatility and reliability of the PT6. We have consistently taken advantage of aerodynamic and material technology advancements to enhance the performance of the PT6 without significantly increasing its size."
